Thread: Question
Hello! Just a generic question for advocacy. Is it possible for someone willing to advocate PostgreSQL usage (like me ? ;) ) within a specific language (in my case PHP) to use an email signature promoting PostgreSQL usage/advocacy ? I write to a number of public mailing list (PHP developers list etc) and it could be a good way to attract the interest of PHP developers. example: " Regards, David Costa, PostgreSQL Volunteering Advocate OR is there such a thing as "Advocacy group" ? link to postgresql site http://postgresql.org $myemail an elephant ? ;) _______.--, ~( {c .` | |__| ,= | /_/_| |_|\_\ J " Just wanted to be sure that is possible and doesn't bother anyone. I do feel that there is a great yet unexploited potential. An email signature can't change it over night but.. why not ? Cheers David Costa

Hey David, we do have an quasi-official advocacy group that consists of Josh Berkus, Bruce Momjian, and myself. However there are certainly a large number of folks outside of that group who do advocacy work so don't let that stop you. I wouldn't see any issues using a sig like "PostgreSQL Advocate", would that work?

Yes. In fact, if you take on specific duties requiring regular contact with the public, you can even get an @postgresql.org e-mail address. -- -Josh Berkus Aglio Database Solutions San Francisco

I think I can concentrate my efforts within the PHP community.

Hmmm.... Thinking of PostgreSQL vs MySQL vs. Firebird..... Unfortunately most of my complex queries are 8-10 lines long and use features such as subselects and UNION statements. Those will show the difference between MySQL and PostgreSQL, but should work in Interbase/Firebird. I am afraid the request to demonstrate the logic power of PostgreSQL in one line is sort of like asking for a proof to Fermat's Theorem in one double-spaced page and normal font size. If someone can do this, I will be quite impressed :-P Maybe a really simple PLPerl function might be a good idea? Best Wishes, Chris Travers

better might be a plphp function

I think any query fiddling with metadata is a bad idea for a sig. I would say overriding function calls in a single query would make great example. After all O in ORDBMS is for overriding..:-) How about declaring a contest on general? An event always stirrs up creativity. Shridhar
Anyone with something simple like SELECT from bestdatabases where logic_power.....opensource.... something not that complicate. Imagine we have a table with a number of relational databases listed.

How 'bout this:
regression=# SELECT s.a[p.i[1]] || s.a[p.i[2]] || s.a[p.i[3]] ||
s.a[p.i[4]] || s.a[p.i[5]] AS "The Best" FROM (SELECT
ARRAY['gre','S','Post',chr((ascii('X')::bit(32) #
9::bit(32))::int),'L']) AS s(a), (SELECT
string_to_array('3,1,2,4,5',',')::int[]) AS p(i);
The Best

Wow! thanks a lot for your input and to everyone who spend some if his
valuable time on this. Eventually I opted for a simple php connection
string using Pear DB as an abstraction layer, you can see it below.
Thanks again ;)

Of course. I was simply demonstrating a query class that is complicated
which many databases probably don't support, PostgreSQL didn't until
recently, but is in the spec.

How about:
SELECT * FROM tab ORDER BY random() LIMIT 5
to pull 5 random rows from a table.
